It is the end of $2024.$ You $($foolishly$)$ played the lottery and won the following cash flows, to be paid at the end of each year:

$\backslash$table$[[$Year$,2025,2026,2027,2028,2029],[$Cash flow,$1,400,1,600,1,800,2,000,2,200]]$

The appropriate interest rate is $11\%.$

Part $1$

Attempt $\frac{1}{3}$ for $6$ pts$.$

What is the sum of present values?

Part $2$

Attempt $\frac{1}{3}$ for $6$ pts$.$

Now assume that the interest rate is $9\%.$ What is the present value of all cash flows?

Part $3$

Attempt $\frac{1}{3}$ for $6$ pts$.$

Now assume that the interest rate is $15\%.$ What is the present value of all cash flows?

Please explain how to complete with a financial calculator also.
